Understanding PSI Readings in Singapore: How to Protect Yourself from Air Pollution

Singapore's Pollution Standards Index (PSI) is a measure of the air quality in the country. The PSI is calculated based on the concentration of five pollutants: particulate matter (PM10 and PM2.5), sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO). The PSI is reported on a scale of 0 to 500, with higher values indicating worse air quality.

What is a "Good" PSI Reading?

According to the National Environment Agency (NEA), a PSI reading of 0 to 50 is considered "good" air quality. This means that the air is clean and there is no significant risk to health. However, people with respiratory conditions may experience some discomfort.

What is a "Moderate" PSI Reading?

A PSI reading of 51 to 100 is considered "moderate" air quality. This means that the air is still relatively clean, but there is a slight risk to health. People with respiratory conditions may experience more discomfort, and healthy people may experience some irritation.

What is a "Unhealthy" PSI Reading?

A PSI reading of 101 to 200 is considered "unhealthy" air quality. This means that the air is polluted and there is a risk to health. People with respiratory conditions may experience serious health problems, and healthy people may experience significant discomfort.

What is a "Very Unhealthy" PSI Reading?

A PSI reading of 201 to 300 is considered "very unhealthy" air quality. This means that the air is heavily polluted and there is a serious risk to health. People with respiratory conditions may experience life-threatening health problems, and healthy people may experience severe discomfort.

What is a "Hazardous" PSI Reading?

A PSI reading of 301 to 500 is considered "hazardous" air quality. This means that the air is extremely polluted and there is a very serious risk to health. People with respiratory conditions may experience fatal health problems, and healthy people may experience extreme discomfort.

How to Protect Yourself from Air Pollution

There are a number of things you can do to protect yourself from air pollution, including:

• Stay indoors: When the PSI is unhealthy or higher, it is best to stay indoors as much as possible. If you must go outside, wear a mask to protect your lungs.
• Avoid strenuous activity: When the PSI is unhealthy or higher, avoid strenuous activity that can increase your breathing rate and exposure to pollutants.
• Drink plenty of fluids: When the PSI is unhealthy or higher, it is important to drink plenty of fluids to stay hydrated and flush out toxins.
• Eat a healthy diet: Eating a healthy diet can help to protect your lungs from the effects of air pollution. Foods that are rich in antioxidants, such as fruits and vegetables, can help to reduce inflammation and protect your cells from damage.
• Take medication: If you have a respiratory condition, it is important to take your medication as prescribed. This can help to protect your lungs from the effects of air pollution.

Effective Strategies for Reducing Air Pollution

There are a number of effective strategies that can be implemented to reduce air pollution, including:

• Reduce emissions from vehicles: Vehicles are a major source of air pollution. Governments can implement policies to reduce emissions from vehicles, such as promoting the use of public transportation, encouraging walking and biking, and requiring stricter emissions standards for new vehicles.
• Reduce emissions from power plants: Power plants are another major source of air pollution. Governments can implement policies to reduce emissions from power plants, such as requiring the use of cleaner fuels and investing in renewable energy sources.
• Reduce emissions from industry: Industry is also a major source of air pollution. Governments can implement policies to reduce emissions from industry, such as requiring the use of cleaner technologies and investing in pollution control measures.
• Increase green spaces: Green spaces can help to improve air quality by absorbing pollutants. Governments can implement policies to increase green spaces, such as planting trees and creating parks.
• Educate the public: The public can play a role in reducing air pollution by making informed choices about their transportation, energy use, and other activities. Governments and non-profit organizations can implement education campaigns to help the public understand the causes and effects of air pollution and how to take action to reduce it.
